Well about a month ago my computer randomly began crashing going to the BSOD, I have not had time to write the number down because it goes away so fast. This usually only happens while I am playing two games Warcraft 3 and STALKER. My system specs are... '
 GIGABYTE GA-P35-DS3R LGA 775 Intel P35 ATX Intel
 EVGA 320-P2-N815-AR GeForce 8800GTS 320MB 320-bit GDDR3 PCI Express x16  
 Western Digital Caviar SE16 WD3200AAKS 320GB 7200 RPM 16MB
 Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
 Intel Core 2 Duo 2.667GHz
 Corsair 550W PSU
Running Windows XP SP 2. Purchased this comp at the end of '07 summer and no problems until this. I have ran memtest and it showed 0 errors, also ran all adaware/antivirus programs I had. Core temps never go above 30c.'
 
Please help, any advice would be nice. Thank you

If you can get it to do it consistently i would start removing things, ie ram, video card, if you have another one to test with, and see if one of those 2 are the culprits. Also memtest is a great proggy, really it is, but it doesnt test the ram all the way, case in point, when i got my new comp built together i had nvidia driver failure errors, i went and downloaded memtest and ran it mulitple times, thinking that was what it is, after a while i began to doubt the brand spankin new videocard i had just bought, for kicks and giggles i removed a stick of ram, and was able to get it to crash again, pulled that stick put the other one in, and it ran nice and stable, point is software is nice, but it isnt something you can wholeheartedly rely on, sometimes the old methods are the best, and in my case, it kept me from lookin like a fool sending in a videocard that was working just fine.

It might have something to do with a CPU overclock or something, are you overclocking, maybe you might want to loosen the timings on the ram as well.

I don't have extra ram or video card to test with. Also I am not overclocking just running basic everything. How would I go about loosening the ram timings?

If your not overclocking then its not the timings, the stock ones should be working just fine.

Ok, it might seem you need to reformat then, i guess no other option

If it crashes ONLY during games, possibly problems with drivers, temps, or power. Yes, I know you said your temps are good. And you have a better than average PSU.

Is there any way to check if its the drivers, should I uninstall than reinstall the latest nvidia ones? If nothing else works than i'll hopefully reformat and all will be fine.

Select the 'Advanced' tab > and under 'startup and recovery' click the 'settings' button. This will open a new window, and under the 'System Failure' heading, uncheck 'Automatically restart.'
 
This should let you read the info on the BSOD. The most common problem for your set up could be graphic drivers.

Ok so finally my computer blue screened again and I had the chance to write down these numbers, Ox0000008E,OxC0000005, OxB6D8600B, OxB5c6071C, Ox00000000 and this RtKHDAUD.sys - B6d8600B, B6D16000,47EA2755.
If someone knows what is wrong or thinks they know what is wrong please post. This usually happens about once a week at moments of high activity in games, particularly Warcraft 3.

It is a problem with the audio drivers. RtKHDAUD.sys is the Realtek HD Audio Function Driver. Un install the driver and reinstall new drivers or get a cheap PCI sound card.

Thank you, I will uninstall the new ones and try to find old ones to install. Hopefully this works, ill post again next blue screen.

I have a similar audio problem with my old a8n-sli premium with realtek audio. If I install the latest nvidia 4in1, the audio doesnt work right. Of course after 6 months I forget and install the new mobo drivers before a new game or video card and then have to roll back the audio driver to get the surround audio working properly over optical out.
